Hi,

Hi,


The most common cause for the loss of picture is a bad Horizontal Output Transistor (HOT). but I would suggest you get a detailed estimate. I think that this would cost you about $60.

The horizontal lines means the vertical amplifier or deflection system has failed. There are over 100 components in this section and any one of them, or most of them can be at fault. However, the most common failure is the VOT or vertical output transistor (which is often buried inside a chip).

The repair will cost around $250 plus or minus.

FEW TROUBLESHOOTING STEPS YOU CAN TRY:

ONE: Do a hard reset (just to make sure there is nothing in the coding that is fowling things up). Unplug the power cord; leave it disconnected for 4 hours. That will restore everything to factory defaults when you power it back up.

TWO: Do the "whacking test" by banging your fist on a few strategic places to see if there are any cold solder joints or loose wires acting up inside the set.

If the above steps don't solve ur problem then I suggest you to go for a repair..

Goodluck..

SOURCE: horizontal blue lines with a slight blue wash in the screen

Hi,
Its because of Over Voltage of Screen (G2) to Blue CRT.
Take off front lower cover (speaker grill) and unscrew board. There you will need to find Focus Block mounted having 6 control knobs. 3 knobs are for Focus control and 3 are for Screen volts control. Find Blue Screen control knob and turn is Counter Click Wise slightly until bluish shade disappear on screen including few blue horizontal lines.
If you select AV input to adjust that will be fine as you do not need to wait for dark-scene.

SOURCE: Mitsubishi TV had horizontal lines across the screen and rolls up

Answer
ONE: Yes, the speaker mounted close/near to the set can be a cause of mischief; please move it further away and see if that helps clear up the problem. But, you must keep it away for several days before you will know for sure because it takes some time to degauss all the internal parts that may have become corrupted by the magnets in the speaker.

TWO: Yes, any set can be repaired the question is cost and wisdom. Old sets are sometimes not worthy of the repair simply because of the likelyhood that another failure will follow soon after. A big screen always invokes a repair charge of $200 and up. After a few of these you will wish you had put all the money into a new set!

THREE: The lines are most likely a problem in the vertical blanking circuits of the set. These are horizontal retrace lines that are supposed to be blanked out during vertical retrace of the raster. Think of it as a paintbrush that scans across the screen painting thin lines and when you get to the bottom of the screen it goes quickly back to the top, but during that time the horizontal, which is many times faster, has made several sweeps; so it must be blanked out during the retrace. The repair involves finding the guilty parts and replacing them. Usually this repair runs over the $200 somewhat.

FOUR: Prior to calling in a service tech try a hard reset to see if that will recover any of the circuit degradations. Merely unplug the power cord and leave unplugged for 4 hours or more. It may help. Or, it may not help; but worth a try since is won't cost you anything.

If the set is over 5 or 6 years of age it probably is not a condidate for any expensive repair. On the other hand, it is a Toshiba - and they make a fine set.

Hope this helps. Let me know if you have further thoughts.

I have amonitor 32 inch when i turn it on i see meany horizontal lines this lines colored how can i solve this proplem pls?


Hello When you get horizontal line, especially colored, it typically means there is a problem internally: either with the LCD inverter (backlight), LCD Circuit board (interprets incoming signal) or the Display panel itself. Sometimes shaking it around can clear up the issue slightly but for the most part it's time to get a new screen. If you have pictures I can verify this is the issue. Any other questions, feel free to ask.

I have red horizontal lines across my entire screen. The lines are noticable. However, I still have a clear picture.


I fixed my problem: it was the screen voltage.
To (try to) fix it: open up your tv, look for a thing like this:
3ee50f1.jpg
As you can see it has 3 control-screws. one of these is for the screen (it has the text 'screen' near it), turn it slightly to the left to reduce the voltage, and the lines will probably disappear.

Picture has horizontal lines that move to middle of screen........


Just got this fixed. The problem is the 21 (yes, 21) main capacitors. It'll only get worse if they aren't replaced. The whole screen'll start jumping, multi-hour "warm up" times until you get a clear picture, maybe not even then... it isn't pretty. Just nip it in the bud now, and more power to you if you tackle it yourself. A good repair shop ought to be able to do this for under $400 if you can't.

Horizontal 'pinstripe' lines on all channels


sound like the screen control on the flyback is set just a little too high. the flyback has the red wire attached to the tube. the flyback has 2 small adjustable controls. if you look close enough 1 is marked focus & on is screen. turn the screen slightly to the left & look at your picture. the screen is like a master brightness & if it's up too high you will see what is called retrace lines. good luck.
